摘要： A plurality of upstream main exhaust passages extend from cylinders of an engine. A downstream main exhaust passage is connected to the upstream main exhaust passages. A main catalytic converter is mounted in the downstream main exhaust passage. A plurality of upstream bypass exhaust passages extend from the upstream main exhaust passages. Each upstream bypass exhaust passage has a sectional area smaller than that of the corresponding upstream main exhaust passage. A downstream bypass exhaust passage is connected to the upstream bypass exhaust passages and has a downstream end connected to the downstream main exhaust passage at a position upstream of the main catalytic converter. An auxiliary catalytic converter is mounted in the downstream bypass exhaust passage. A gas flow switching device is provided which is capable of forcing the exhaust gas from the cylinders of the engine to flow toward the upstream bypass exhaust passages when assuming a given operation position.
